FARM-GATE.

Specification of Letters Patent.

Patented Sept. 26, 1911.

Application filed November 17, 1910. Serial No. 592,924.

To all whom it may concern.

Be it known that I, LEONARD Z. PRESTON, a citizen of the United States, residing at Scottsville, in the county of Mitchell and State of Kansas have invented certain new and useful Improvements in Farm-Gates, of which the following is a specification.

This invention relates to gates and has particular references to an improved farm gate.

An object of this invention is to peculiarly form a gate for farms whereby the gate may be adjusted to separate stock by raising the gate to various heights to allow stock of different sizes to pass beneath the gate.

The invention has for another object to form a gate which may be operated from the sides thereof and at a distance from the gate so that the gate may be opened and closed by the operator when in a vehicle without getting out of the same.

The invention further contemplates an improved locking pin which is adjustable so as to hold the gate at various heights in separating the stock.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings in which Figure 1 is a perspective view of the improved gate closed. Fig. 2 is a side elevation of the same disclosing the gate partially raised. Fig. 3 is a detail view of the supporting pin and its adjusting members. Fig. 4 is a detail perspective view of one of the operating crank-arms and its connections. Fig. 5 is a detail perspective view of the cam block and the retaining pin carried by the gate. Fig. 6 is a detail perspective view of the connector for attaching the inner ends of the chains to the gate-head. Fig. 7 is a detail perspective view of the hinge-bails connecting the forward ends of the chains to the gate-head. Fig. 8 is a transverse sectional view through the head of the gate.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters. Referring to the drawings the numerals 10 and 11 designate spaced standards or posts between which the improved gate is hinged. The gate is formed of a plurality of longitudinal beams 12 reinforced by diagonal braces 13 and vertical bars 14. The inner end of the gate is provided at its lower corner with a head comprising a block 15 seated in the body of the gate, and lateral plates 15 disposed against the opposite sides of the block 15 providing a substantial support for the gate. A pin 16 is carried by the standards 10 and 11 and passes through the block 15 and lateral plates 15, the pin 16 being provided with a roller 17 which is seated in the block 15 and held in position by the lateral plates 15. The pin 16 passes loosely throughthe roller 17 and serves to reduce the friction caused by the swinging of the gate. The gate is provided with a counter-balance weight 18 which is attached upon its inner end. and adjacent to its upper edge. A gate-post 19 is disposed in registration with the outer end of the gate and is provided with a recess 20 in its upper edge for the reception of the extension 12 of the upper longitudinal beam of the gate for holding the gate in position. The upper end of the gate-post 19 is provided with inwardly and oppositely beveled edges 21 terminating in the recess 20 for the purpose of guiding the extension 12" into the recess when the gate is closed.

The gate is provided with a latch-bolt 22 arranged in a housing 23 positioned between the two longitudinal beams 12 and against the inner edge of the outer vertical bars 14. A spring 24 is disposed within the housing 23 and arranged about and connected to the sliding latch 22 for the purpose-of normally extending the same. The gate post 19 is formed with a shouldered recess or opening.

25 for the reception of the outer extremity of the latch-bolt 22 when the gate is closed.

An operating cord 26 is attached to the inner end of the sliding bolt 22 and passes inwardly to the central vertical bar 14* where it passes over a pulley 27 and up to the upper edge of the gate. A second pulley 28 is mounted upon the bar 14 and receives thereover the cord 26 which passes to the inner end of the gate.

Outer posts 29 and 30 are arranged in registration with and spaced from the standards 10 and 11 at the opposite sides of the gate. A pair of shafts 31 and 32 are journaled across the upper ends of the standards 10 and 11 and the posts 29 and 30, and carry upon their inner ends sprocket wheels 33 and 3 1 which are arranged against the opposite sides of the gate and against the inner faces of the standards 10 and 11. The sprockets 33 and 34 carry chains 35 and 36 having their extremities secured against the opposite sides of the head of the gate and spaced from the opposite edges of the posts 10 and 11. The inner ends of the chains 35 and 36 are carried upon a connector 37 which is in the form of a bolt having an enlarged head 37 against the inner side of which an enlarged bearing portion 37 is formed to receive a hook 37. The enlarged portion 37 b provides a shoulder seating against the outer face of the block 15 to admit of the binding of the connector 37 in position and at the same time providing a space for the reception of the hook 37. The opposite end of the bolt 37 is provided with a nut 37 having a sleeve portion 37 against its inner face adapted to ride over the bolt 37 and bind against the opposite side of the block 15. The sleeve 37 carries the opposite hook 37. The forward ends of the chains 35 and 36 are hingedly attached to the lower forward end of the block 15 by bails 35 and 36 which are attached respectively to the chains. Each of the bails is preferably formed of a U-frame bent angularly at its corners and provided at its outer corner in registration with its respective chain, 35 or 36, with a hook 35 and 36 The free ends of the bails 35 and 36 are provided with eyes 35 and 36 which receive therethrough a pin 36 t0 hingedly support the same. The bails 35 and 36 straddle the inner bar 14 of the gate and swing under the action of the chains 35 and 36 to support the outer end of the gate. The outer extremities of the shafts 31 and 32 carry crank-arms 38 the sleeves 39 of which are provided with segmental blocks 40 fitting into a semicircular recess 41 formed in the side of each of the shafts 31 and 32. The segmental blocks 40 are considerably reduced from the size of the recess 41 to admit of lost motion between the crank-arms 38 and the shafts 31 and 32.

Fixed upon the outer ends of the shafts 31 and 32 and against'the inner sides of the sleeves 39 are radial arms 42 which are provided in their outer ends with openings 43. The crank-arms 38 carry apertured ears 44 formed upon their inner edges for the reception of the inner extremities of the cable sections 26 and 26 which branch from the inner end of the operating cord 26 and pass through the sprocket wheels 33 and 34 and the openings 43 in the radial arms 42.

The improved means for holding the gate at various heights to allow stock of various sizes passing therebeneath comprises a tapering pin 45 which is hinged upon a bolt 46 midway of its ends and carries upon its upper extremity an arcuate-bar 47 which is provided with a correspondingly formed longitudinal slot 48. The bar 47 is hinged upon the upper or enlarged end of the tapering pin 45 and is adjustably clamped against the side of the housing 23 by a clamping bolt 49. The bar 47 is employed in holding the pin 45 in various angles so as to engage the pointed extremity of the pin against the inner side of the gate-post 19. A cam block 50 is carried against the side of the gate and receives centrally therethrough the bolt 46 which supports the pin 45. The block 50 is provided with shoulders 50 and 50 receiving the opposite edges of the pin 45 to limit and to hold the same respectively in an extended or a retracted position. The bolt 46 is provided upon its outer end with a sleeve 51 receiving across its inner face one end of a helical spring 52 which is interposed between the sleeve 51 and the pin 45. The spring 52 is employed in holding the pin 45 against the shoulders 50 and 50 lVhen it is desired to open the gate the operator grasps the crank-arm 38 and rotates the same to turn the sleeve 39 upon the shaft- 32 and away from the radial arm 42. This initial movement in the operation of the gate draws the cable section 26 taut and moves the cord 26 inwardly to retract the latch-bolt 22 from the opening 25. The cable section 26 is so adjusted that when the latch-bolt 22 is completely withdrawn from the opening 25 the block 40 strikes against the marginal edge of the opening or recess 41 and effects the rotation of the shaft 32 upon the further movement of the crankarm 38. As the shaft 32 is revolved the sprocket-wheel 34 is turned therewith to cause the operating chain 35 to travel over the sprocket 34 and swing the gate about the pin 26. In closing the gate the reverse operation takes place in which the handle or crank-arm 38 is rotated in the opposite direction to first slacken the cable section 26? and allow the spring 24 to return the sliding bolt 22 to its normal extended position. The block 40 strikes the opposite marginal edge of the semicircular opening 41 and revolves the shaft 32 in an opposite direction to rotate the sprocket-Wheel 34 therewith. This operation causes the operating chain 35 to travel over the sprocket wheel 34 and return the gate to its normal closed position.

When it is desired to open the gate to provide a small space therebeneath, the gate is raised by swinging one of the arms 38 or by lifting the bolt 46. When the gate is raised the clamping bolt 49 is released from the arcuate bar 47 and the pin 45 is turned into the desired angle against the outer shoulder 50 to extend the extremity of the pin 45 in the path of the gate-post 19 to engage therein when the gate is dropped. The arcuate bar 47 serves the function of holding the pin 45 in the adjusted angle and to retain the same from displacement from the shoulder 50 Fig. 2 of the drawings discloses the pin 45 adjusted against the shoulder 50 and movement therewith.

showing the extremity of the pin 45 engaging against the inner face of the gate-post 19 to hold the gate in a raised position. When the gate swings about the supporting pin 16, the roller 17 revolves and reduces frictional contact between the pin and the gate. The roller 17, as will be noted from Fig. 2 of the drawings is disposed within an arouate slot through the head and is adjustably held in either end of the slot by the provision of a retaining block 17". It will be noted from Fig. 8 that the roller 17 is of a length equal only to the thickness of the block 15 and that its ends abut against the inner faces of the lateral plates 15.
